The analytical calculation of absorption in multifaceted crystals

Clark, R. C., Reid, J. S.·1995·Acta Crystallographica Section A Foundations of Crystallography

Abstract

The exact analytic method of evaluating the absorption during scattering in multifaceted convex crystals is developed in a way that permits efficient computation. A fast and accurate algorithm is given for finding the Howells polyhedra whose determination is fundamental to the analytic method. The algorithm allows for the evaluation of cases when the sample is only partly illuminated, can be adapted to more general situations and can be used to generate an estimate of the error in the computation. In most cases this is to 1 part in 1014. Results of standard tests are given to greater accuracy than previously available and results for multifaceted approximations to a cylinder and a sphere are given to illustrate the power of the method.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
